After going through some posts here and some others on Blizzard Forums I don't have a clear understanding of the internal cooldown of Windfury. Posts are ranging from 3 seconds up to 40 seconds.
From a Dagger Rogue perspective I also would like to better understand the mechanics of GoA versus Windfury when having an Enhancement Shaman in my group. From my experience during 10 and 25man raids I gained more sustained dps through GoA Totem than through Windfury (measured through SWS Stats 2.1.1).
I would be very thankful if experienced 25man Raiders could help out on my questions.
